SHEET-METAL ROOFING.

SPECIFICATION forming part of Letters Patent No. 518,089, dated April 10, 1894.

Application filed June 8.18%. Serial No.476,978. (in model.)

To all whom it may concern;

3e it known that I, EDWIN D. BEVI'IT, a c tizen of the United States, residing at Oinc1nnat1,in the countyv of Hamilton and State of Ohio, have invented a new and useful Improvement in Sheet-Metal Roofing, of which the following is a specification. My invention relates more especially to an lmprovement in the roofing for which United States Letters-Patent N 0. 422,178 were grant ed to me February 25, 1890. Part of this invention formed part of the original application for said Letters-Patent, and was divided therefrom.

The novel features of construction and their mode of application will be fully hereinafter described and particularly pointed out in the claims. 1 p In the accompanying drawings,Figure 1 1s a broken perspective View of a cleat-cap embodying my invention; Fig. 2, an end view or a plain-fianged sheet, to which form of roofing my cleat-cap is peculiarly adapted; Flg. 3, a broken, transverse section showing the manner in which several adjacent plainfianged roofing-sheets are united together and secured in place on'the sheathing by means of my cleat-cap, the seam thereby formed be- 1ng left open in this View preparatory to the final closingpass of the usual crimpingtool; Fig. 4, an end elevation of my cleat-cap; Fig. 5, a broken, inverted perspective of Fig. 1; Flg. 6, a longitudinal, sectional elevation of my cleat-cap, taken on line 00, m, of the'inverted-view Fig. 5; Fig. 7, a bottom-plan view of a single width or narrow strip of flat or plane sheet-metal used in constructing my cleat-cap, slits being shown out along one edge thereof whereby the fastening-cleats are formed, and constituting the first step in making my cleat-cap; Figs. 8, 9, 10, and 11, views similar to Fig. 7, showing the several steps through which said fiat narrow strip or single width of metal passes in making it into inverted-V shape in cross-section and properly bending and disposing the series of laterally-projecting cleats thereon, the last-named View, (Fig. 11,) being a bottom-plan of my invention in its completed state ready for use; Fig. 12, a bottom-plan view similar to Fig. 7, but of a Wider strip of plane sheet-metal which I utilize in forming two of my cleat-caps; Fig.

13, a bottom-plan view, showing the strip seen in Fig. 12 with my preferred arrangement of slits cut therein, intermediate its longitudinal edges; Fig. 145a plan view showing two strips resulting from the slitting-operation seen in the preceding View; and Fig. 15, a plan view metal or cap, fitting over contiguous flanges a of paralleladjoining sheets, and forminga closing-joint or seam therefor. I

19 represents each one of a series of transverse or lateral cleats formed along said cap B, and whereby it is secured in place on the sheathing. These cleats b are preferably constructed integral with the cap, those shown in the drawings being formed on one limb thereof, similar to those shown and described 1 in connection with they inverted-V-fiange in said former Letters-Patent. In Figs. 7, 8, 9, 10, and 11, I show how the cleats are formed along one edge of a single width or narrow strip of plane or flatsheet-metal; and in Figs. 12, 13, 14, and 15 I show how the cleats are formed along a wider strip or sheet of similar material, and out of which two caps with cleats are constructed on a somewhat more speedy and economical plan.

In one process, (the first above-named,seen

in Figs. 7, 8, 9, 10, and 11,) of forming my cleat-cap, I take a narrow width 0 of plane sheet-metal, and provide or cut longitudinal end-slits c, c, and intermediate right-angled slits c, 0, along one edge thereof, as most clearly shown in Fig. 7, and similar to the slitting seen in said former Letters-Patent. The narrow strips of metal thus partially severed from the main-piece, are then lapped over atd so that the respective folds thus formed lie at forty-five degree angles to the edge of the said main-piece, and said strips too project laterally at right angles to said edge, as shown in Fig. 8. The said narrow strips and the same width of unslitted metal d on the edge of said main-piece are then folded over onto the bottom of said piece, as shown in Fig. 9, the line of fold being indicated by dotted lines 1, in Fig.8, and forming the webs which connect the cleats to the main cappiece. The main-piece with its cleats and folds are then placed in the die to give'the inverted-N shape, in cross-section, (best seen in Fig. 1,) and the cap is now complete ready for use. I

In the other process, (the second abovenamed, seen in Figs. 12, 13, 14, and 15,) of forming my cleat-cap, and which is the preferred form, (on account of both speedand economy as hereinbefore stated,) I take a pieceD of metal whose width is double that of the piece seen in Fig. 7, less the width of metal used in making the cleats in said firstnamed process; a double row of longitudinal end-slits e, e, and right-angled slits f, re-

spectively, are then made down the center of said piece D, the space or width of metal between said double-row of slits corresponding to that necessary in forming the cleats b. This slitting-operation results in the parting or division of the piece D into the two slitted pieces or lengths D, D seen in Fig.- 14, the slit-ted portions or strips so provided being then lapped over and disposed sidewise to form the lateral cleats, and the whole subjectedto the die or other suitable tool for converting into inverted-V shape in cross-section, as hereinbefore stated in connection with the firstnamed process. The dotted lines 2 in Figs. 8, 9, 13, 14 and 15, indicate the centers or lines on which the pieces 0, D, and D are bent, and constitute the apexes of said inverted-V caps when complete. The narrow unslittedportions 9 of the metal in pieces D and D correspond to those d, above mentioned, and, while they are somewhat shorter, they fully answer the purpose of connecting the cleats to the said pieces D and D In thus cutting and slitting the piece or sheet D and forming two cleat-cap divisions D and D therefrom, which is less in width than two of said singlewidth pieces 0, as stated, the saving in time, labor, and metal is quite material, and while one less cleat results in the same length of piece for each cap, still I secure six cleats in the two pieces D and D combined, while there is but four in practically the same width and length of metal, secured in the piece 0. In Fig. 15, it will be clearly seen that the op-. posite ends of both pieces are free from cleats or double thicknesses of metal owing to the provision of said end-slits e, e, as above set forth, thus readily adapting the said ends to be suitably bent or folded, or otherwise manipulated, as desired.

In placing the plain-flanged sheets (scen in Fig. 2), togetherto form a roof, mycleat-caps are applied to each joint or contiguous pair of upturned-flanges a, a, as best seen in Fig. 3, wherein the flange of one sheet stands upright under one limb or side E of the cap, and the adjoining flange of the next sheet stands upright under the otherlimborcleatedside F of the cap, the flangedside of the lastnamed sheet resting on the cleats of the cap, which cleats have been previously nailed or otherwise secured in place on the sheathing.

It will be seen that in the use of my cleatcap and the ordinary flanged roofing-sheets, herein described and shown, a roof can be very readily, substantially and economically made and repairs thereto greatly facilitated over any form heretofore in use.

I claim- 1. As a new article of manufacture, an anchor-cap for standing-seam roofing, composed substantially of a narrow sheet or plate formed into an inverted-V shape in cross-section, an inner integral fold or strip turned along one edge or side of said sheet, longitudinal endslits c, c, and intermediate right-angled slits c, c, constructed along the line or web of said fold, and narrow strips of metal, thus partially severed from said cap or mainpiece, lapped under at d and bent and disposed laterally across the bottom of the cap, to form anchoring-cleats b, as herein shown and described. I

2. In the construction of a joint-cap for sheet-metal roofing, the process herein-described of taking a strip or piece D of less width than that of the combined width of the metal requisite in two single caps, making a longitudinal, double-row of end-slits e and e, and right-angled slits f, down the center thereof, the space or width of metal between said double-row of slits corresponding to the width of metal necessary in forming the cleats along both resultant divisions D and D of said piece D, the narrow strips provided by said slits then bent and disposed into lateral cleats and connecting webs, and the divisions D and D and parts of said cleat-strips being then pressed or otherwise formed into inverted-V or other suitable shape in cross-section, substantially as herein set forth.

In testimony of which invention I have hereunto set my hand.

EDWIN D. BEVITT.
